Weekly Outlook: December 28, 2020 – January 3, 2021

We’ve reached the final days of 2020, but there may still be a little mayhem on the horizon.

We start the week out on a rather mild note. Low pressure will head up the St. Lawrence Valley today, bringing in some clouds but also milder weather. There could be a shower or two, but the bulk of the precipitation associated with this storm will stay to our north and west. The storm drags a cold front across the region at night, putting an end to our brief mild spell. Breezy and colder conditions settle in for Tuesday as high pressure starts to build back in. Wednesday also looks to be on the cold side, but should be less windy, so it won’t feel as cold.

This brings us to the final day of a year that most of us are all too happy to see end. Another low pressure area passes to our north and west, with milder conditions once again and some rain showers, though it does look like it should be dry for midnight if you are planning to be out and about. However, the cold front trailing that system will likely stall out near or just south of the region while high pressure tries to build in from the north early on New Year’s Day. Another low pressure area will start heading toward the Midwest that day as well. The front to our south will try to head back northward as a warm front, but with high pressure to the north, cold air may remain in place at the surface, especially across the interior. As the precipitation starts to move in, we may have warm air aloft and cold air at the surface, which would be a recipe for freezing rain. Obviously, being this far out, things will likely change, but we could be looking at icing, possibly some significant icing, across the interior. This system will take it’s time moving toward the region, so even though the warmer air should eventually win out and change everything to plain rain, the rain may continue into Saturday before winding down. High pressure builds in on Sunday with drier and cooler weather. We should have some additional clarity on this situation later this week in our Weekend Outlook, which may be published on Wednesday again.

The models don’t agree on what type of precipitation we’ll have on Friday, or whether we’ll have any at all. Images provided by Pivotal Weather.
